ABSTRACT:
A process for clarifying liquors containing suspended solids is disclosed. The process is applicable to liquors having concentrations of suspended solids ranging from low to high, typically between 0.5 and 40 gm/l. The clarification process is characterized by the addition of flocculent and in excess of 50 gm/l inert particulate material so as to cause the formation of flocs comprising suspended solids and inert particulate material thereby to separate the suspended solids from the liquor. The inert particulate material is selected from silica sand, magnetite, limestone, ilmenite, hematite and calcite.
